Geologic Background:
Glacier Peak is not prominently visible from any
major metropolitan centers, and so its attractions, as
well as its hazards, tend to be overlooked. Yet, Glacier
Peak has produced larger and more explosive eruptions
than any other Washington volcano except Mount St.
Helens. In the past 14,000 years, Glacier Peak has
erupted at least a dozen times, most recently around the
eighteenth century.
Historic Activity:
- No eruption activity has occurred during at least
the last 150 yrs.
Recent Activity:
- Three hot springs surround the volcano and warm
ground.
